FAQ
Frequently Asked Questions
Answers to common research and ordering questions.
What does Research Use Only mean?
All Groppi American Peptides materials are supplied strictly for laboratory research. They are not intended for human or veterinary use, diagnostics, or any therapeutic application.
Do you provide a Certificate of Analysis?
Yes. Published lots have a third-party Certificate of Analysis available as a PDF in the COA Library, searchable by accession number. Lots still under third-party testing are labelled accordingly.
How is purity determined?
Independent laboratories analyse each published lot using HPLC and LC-MS methods. The full report is published unedited in the COA Library.
Can I verify a lot number?
Yes. Use the Batch Verification page or scan the QR code on the vial label to open the exact COA record for that lot.
Do you publish dosage or administration information?
No. We never provide dosing, administration, or human-use guidance of any kind. Our documentation covers identity, purity, and handling only.
How should materials be stored?
Follow the storage conditions stated on the COA and vial label for the specific lot. Storage information is handling guidance, not use guidance.
